FREE Teledyne FLIR Thermal Dataset for Algorithm Training

This free Teledyne FLIR ADAS Dataset provides fully annotated thermal and visible spectrum frames for the development of object detection systems using convolutional neural networks (CNNs). This data was constructed to encourage research on visible + thermal sensor fusion algorithms ("RGBT") and to empower the automotive community to create safer and more efficient ADAS and driverless vehicle systems.

Why Use Teledyne FLIR Thermal Sensing for ADAS?

The ability to sense thermal infrared radiation, or heat, provides both complementary and distinct advantages to existing sensor technologies such as visible cameras, Lidar, and radar systems.  The Teledyne FLIR thermal sensors can detect and classify in challenging conditions including total darkness, most fog, smoke, inclement weather, and glare.  When combined with visible light data and distance scanning data from Lidar and radar, thermal data paired with machine learning creates a more comprehensive detection and classification system.
